Showmax : i don't have a subscription , but could watch trailers and it works fine , so sure with subscription the full episodes will work the same.
DSTV Now: like they say this is the android app and not android TV app , so have to sideload , the series plays , and is the same as the mibox app.
Netflix: netflix works - same as dstv , have to sideload app - if you every used android tablet for netflix it is the same.
the positive about the Telkom Box : they said DSTV now will work on the box and Netflix - so have to wait for monochoice to get the updated version of the DSTV now App , not sure if it will be available for the mibox , but Telkom i'm sure will get it just a matter of waiting . same goes for Netflix , sure it is just a simple thing about getting the LIT device added to the DRM allowed list for netflix. there is light at the end of the tunnel. you have a cheap box , with "massive" potential <- (MyBB joke get it massive lol)
it is cheap it does what it says and in time all apps will come and be supported on the device , alot more pros than cons on the device.
it has android 7 , will wait and see if mibox get android 7.
